CI Bill Doctor

What it does

CI Bill Doctor compares workflow YAML and flags cost signals such as matrix expansion, expensive hosted runners, broader triggers, and missing guardrails. Try it locally in your browser or add the free, read-only GitHub Action. Open source and no telemetry.

Find GitHub Actions cost regressions before merge. Scan workflow YAML locally in your browser or add the free GitHub Action, read-only by default.

See when a pull request expands a matrix, moves jobs to expensive runners, broadens triggers, or removes cost guardrails—while the change is still reviewable. Illustration based on a validated public lab result ↗ . Public list-rate signals—not an invoice. Nothing you paste is uploaded, stored, or sent to an AI model. The deterministic engine reports what changed, why it matters, and what remains unknown. Compare runner rates and static matrix fan-out before and after a workflow change. Every finding includes severity, confidence, concrete evidence, and a recommendation. The Action can process recent run metadata ephemerally, with conservative fallback when incomplete.

  "Git who" – A new CLI tool for industrial-scale Git blaming2025 · github.com · ▲252

  I've always wanted a better way to explore the authorship data embedded in a Git commit log. I'm having fun building a CLI tool to do this. It's a bit like the "Contributors" tab on Github that shows you how many commits each contributor has made but much faster and with many more options. If you get a chance to try it out, please let me know. I'd love to hear feedback and suggestions. Thank you!

  See the impact on your cloud costs as you code2024 · ▲179

  Hey folks, my name is Owen and I recently started working at a startup (https://infracost.io/) that shows engineers how much their code changes are going to cost on the cloud before being deployed (in CI/CD like GitHub or GitLab). Previously, I was one of the founders of tfsec (it scanned code for security issues). One of the things I learnt was if we catch issues early, i.e. when the engineer was typing their code, we save a bunch of time. I was thinking … okay, why not build cloud costs into the code editor. Show the cloud cost impact of the code as the engineers are…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
